IC-7400 with SDR panadapter

Our buffer interface named IFace can be used to add an SDR panadapter to the glorious Kenwood TS-850s.

The operations to be carried out are very simple, it is sufficient to obtain from its wiring diagram the information on the points where the IF signal has to be taken. This radio uses several mixers, we are interested in the first of the reception chain as it gives us a broadband signal. The IF frequency is 73.05 MHz. The following images show the block diagram of the radio and where to get the IF signal.

The following images show the portions of the schematic diagram of the RF UNIT where we can see the exact points where to sample the IF signal and the power supply.

We now proceed to identify the exact points on the printed circuit board where to take the IF signal to be sent to the IFace. The following images show the sampling point for the IF signal and for the power supply for the buffer interface.

The use of PTT signal is not required, RX and TX signals are separated.

Panadapter SDR for the TS-440s

To install the IFace card inside the Kenwood TS-440s follow the steps below.

The TS-440s, like other radios, has a fairly complex configuration and uses different intermediate frequencies. We are interested in having a “wide band” signal, so it will have to be picked up before the main bandpass filter. The sequence of operations to be performed to obtain a bandwidth sufficient to realize a panoramic receiver around the chosen IF frequency (45.05 MHz) is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission may not be necessary. The following images show the point where the IF signal will be taken and the power supply.

Now we need to locate the points where to connect the electric cables to the IFace. The following images illustrate where to get the various signals on the RF UNIT.

Installing IFace inside the TS-2000 – VHF and UHF bands

In a previous article we presented how to install the IFace card inside the Kenwood TS-2000 to obtain the IF signal of the HF and 50 MHz bands in order to send it to an external SDR. Now let’s see how to get the IF signal for the VHF and UHF bands. Installation is very easy.

The result you can obtain is well shown in the following video.

The TS-2000, like other radios, has a fairly complex configuration and uses different intermediate frequencies depending on the band on which you are operating. In any case, the one described here is the sequence of operations to be performed to obtain a bandwidth sufficient to provide a panoramic receiver around the IF frequency relative to the VHF and UHF bands.

The point where the IF signal is taken can be identified more precisely using the electrical scheme as shown in the following images. The electronic card of interest is the one named TX-RX2 and the signal can be taken R167 or C233.

Now we need to find out where to get the power supply: energy can be taken from the CN 12 connector or from the CN 17, 14S signal.

  • PTT: for the TS-2000 it is not required because the reception circuit is automatically muted during transmission.

In the images that follow you can see the points where to take the IF signal: therefore the installation is really simple.

You can by IFace 2 simply making click on the buttons below.

SDR interface for the TS-570DG

These are the instructions to install the IFace interface inside of the Kenwood TS-570DG. The installation is very easy.

IFace I/O signal connections

The TS-570DG, like other radios, has a complex configuration and uses different intermediate frequencies. We are interested in having a “wide band” signal, so it will have to be picked up before the main band pass filter. The sequence of operations to be performed to obtain a sufficient bandwidth to realize a panoramic receiver around the chosen IF frequency (73.05 MHz) is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission will not be necessary. The following images show the point where the IF signal will be taken.

Now we need to locate the points where to connect the electric cables to the IFace. The following images illustrate where to get the various signals on the TX-RX UNIT.

SDR interface for the TS-590S

These are the instructions to install the IFace interface inside of the Kenwood TS-590S. The installation is very easy. For the TS-590SG see the note below.

IFace I/O signal connections

The TS-590S, like other radios, has a complex configuration and uses different intermediate frequencies also depending on the band used. This radio requires 2 IFace cards because two intermediate frequencies are used, one at 11.374 MHz and another at 73.095 MHz. We are interested in having a “wide band” signal, so it will have to be taken before the main band pass filter.
The sequence of operations to be performed to obtain a sufficient bandwidth to realize a panoramic receiver around the chosen IF frequency is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission will not be necessary. The following images show the point where the IF signal will be taken.

As you can see below, the radio uses two different frequencies depending on the band chosen: it is therefore advisable to use two IFace interfaces and not to insert a mechanical switch.

Let’s start by analyzing the wiring diagram. We have to find the first mixer and where to take the power supply. From the following image everything will appear clear.

At this point we have to locate the points where we connect the electric cables to the IFace. The following images show where to take the various signals.

Last but not least, don’t forget to provide power supply to the IFace: you can easily find a source inside your radio.
